Once the cool weather finally hits, the Triangle experiences event pile-up as bad as its traffic. This weekend's festival congestion gives you lots to choose from. If you're craving baklava, spanikopita and knee-lifting dance, head on over to the Greek Festival at East Chapel Hill High School, Oct. 6-9. (Admission is free; call 682-1414.) Up for more multinational fare? Check out the music and tunes at the International Festival, Oct. 6 and 7 at the Raleigh Convention and Conference Complex. It's $6 to get in, $3 for children 12 and younger; call 832-4331. In the same town, The 15th Annual Compassionate Living Festival holds court at Four Points Hotel, inviting "all those interested in ethical living" to listen to speakers on "Understanding Animal Liberation," "Why Doesn't Everyone Agree With Me?" (hmm) and the Lorax-like "Speaking for Those Who Cannot." The event runs Oct. 6-8; lectures are $6 each. Check out www.cultureandanimals.org for details. Finally, for the lunar among you, Hillsborough is hosting Festival of the Autumn Moon on Saturday, Oct. 7 (10 a.m. to 6:30 p.m.) at the Burwell School. Expect to find a local showing of food, art, and music and literary personalities, including old-time fiddler Joe Thompson, poet Jaki Shelton Green, Boys of Walltown and more. Call 929-2691 for information.
